I'm watching Mobile Suit Gundam: The Origin, and it feels eerily similar to Dune:
- The Deikuns are the Atreides, led by Zeon Zum Deikun whose death is the spark that begins the entire series just like Duke Leto Atreides
- The Zabi are the Harkonnen, led by an overweight patriarch Degwin Sodo Zabi just like Baron Vladimir Harkonnen
- Casval Rem Deikun is Paul Atreides, who adopts a new name Muad'Dib in order to lead his resistance against the Harkonnen
- Ramba Ral is Duncan Idaho, someone loyal to the Atreides family after being forced to work for the Harkonnens (in this case it would be in reverse order)
- I have yet to discern whether Artesia Som Deikun is like Alia Atreides
I'm only 10 episodes into Mobile Suit Gundam: The Origin and I've never seen the original Mobile Suit Gundam, so spoiler tags appreciated! I don't know if most of The Origin is completely new material based off the manga, or some of these parallels existed in the original Mobile Suit Gundam.
